The invention relates to a self-supporting optical cable bird prevention method, and belongs to the technical field of electric power communication optical cables. The method comprises the technical scheme that a twisted wire bundle (2) is a twisted-pair cable formed by coiling a plurality of twisted wires, is arranged at two sides of a hanging point, and matched with an ADSS (all-dielectric self-supporting) optical cable (1); a shield (3) is a semi-arc shield made of a polyethylene material with the smooth surface, the length of the shield is matched with that of the twisted wire bundle on the ADSS optical cable; on the tail end of the twisted wire bundle on the ADSS optical cable 10cm of the twisted wires are rolled and forms a 90-degree angle with the twisted wire bundle, so that a bird is prevented from standing on and edge of the twisted wire bundle or pecking the optical cable; two holes (4) are formed respectively in two ends of the shield, and two twisted wires respectively penetrates through the two holes in the ends, and the shield is fixed on the twisted wire bundle by the two twisted wires; and the twisted wires at one end, in which the twisted wire bundle is connected with an armor clamp, are fixed on the optical cable, and the shield is fixed at the end through the two twisted wires, so that the shield is prevented from rotating, two ends of the twisted wires can be protected, and the communication failure caused by the woodpecker pecked optical cable can be prevented.
